Description

An attempt of copying information from PGraphics to PImage using get() or copy() clears the PGraphics object if P2D renderer is used. It makes impossible many things, for example using PGraphics (or its copy) as a texture for the shader.

Expected Behavior

successful copying, like with default renderer

Current Behavior

both PGraphics and PImage are empty.

Steps to Reproduce

PGraphics img1;

void setup() { size(300, 300, P2D);

img1 = createGraphics(200, 200, P2D);

img1.beginDraw(); img1.background(120); img1.endDraw();

PImage img2 = img1.get(); // if comment out this line — grey rectangle appears }

void draw() { background(255); image(img1, 100, 20); }
